Gaps between slats are wider than pictures indicate. Unless you get a real high quality mattress with extra support and not one of those foam mattresses, you WILL feel the slats. frame took about an hour to assemble. lots of 3"+ wood screws so make sure to have electric screw driver fully charged. Frame looks nice assembled. A little leary about the pointy boards that keep back propped up. if they wear over time it may become dangerous. This was the most affordable frame I could fine.
